The application should have a one-click choice between original and high contrast colors. For high contrast I propose set, well chosen saturation and light and then equi-distance hue values and it ought to give good result. Authors shouldn't be burdened with this also.

I always change the colours; in fact, I have my favourite colours to play (black and pink or orange). Maybe it is against the intention or the taste of the author, but I prefer to play confortably. Later, when I see the result, I can admire the work of the artist.

The translation of Vrendly's comment: "The colours brown with black, and blue with grey, are quite the same." My own comment: I had to change the colours brown and grey into a different colour, but in general it sia very nice picture and easy to solve, although some parts need some extra attention. Well done!!
